A/N: hey everyone! This is my first ever Smallville fic (yayness!) if you're a fan of Supernatural then check out my other stories. This one came to me when I was on a train (typical. I always pick the hardest place to write)

When Clarke's biological sister comes to earth to help him save the world, will she stir the pot that Clarke calls his life and create chaos?

Rating: PG

Key elements: there's a little romance, absolutely no slash, some violence and a door to a whole new world.

Our new character has several new powers that are being brought in. they are:

Telepathy (mind reading)

Molecular Deconstruction (she can make things go boom)

Hypnotism

Speed

Invisibility

Florae (something to do with plants, wait and see)

Clarke woke to a large humming sound coming through his bedroom window. He looked out and then there was a huge flash of purple light. He instinctively ducked, then peered cautiously over the windowsill. There was a huge cylinder of purple energy radiating off of the ground and into the sky. He pulled on a pair of jeans, then ran down the stairs and into the very early morning light.

He reached the far side of the farm in a matter of seconds and then leant over the newly created crater. A girl of 17 stood inside, looking down at the ground and flickering in and out of sight every so often. Words that Clarke couldn't control escaped from his lips, "Zephirana." The girl looked up and smiled sweetly at him. "hello brother"

He reached down and grabbed her outstretched hand, Pulling her up onto higher ground. "what are you doing here?" he asked and she wrapped her arms around him, "father sent me. He thinks you might need help saving this planet you've grown so fond of" Zephirana said and then crouched over the hole and pulled out a largish bag. "so, when do I get to meet Martha and Jonathon?" she asked excitedly and Clarke shrugged, "now if you want"

They walked back towards the house and Zephirana talked non-stop about their homeland. Then she talked about things she'd destroyed. Clarke stopped, "what exact powers do you have?" he asked and she stopped talking, "the usual. Molecular deconstruction, invisibility, hypnotism, speed, florae and telepathy. I inherited most of them from mother, except speed. We don't exactly know where the molecular deconstructions came from but they're really handy"

She continued walking, "so how's Lana? I see she's got herself a new boyfriend. The assistant coach of the football team. Very interesting" she blurted out and then slapped a hand to her mouth, "whoops. Did I just say that out loud?" Clarke stared open mouthed, "how'd you know all of that?" he asked and she shrugged, "I watch you and this world 24 hours a day. I notice these things"

"ok, well try not to mess up my life. no matchmaking and especially no molecular deconstruction in front of people!" he said and she smiled, "agreed"

A/N: that was a short one. Oh well, onto the next one then…
